Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jul 06 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. Region 2665 (S05E72, Cso/beta) was numbered this period after rotating into view. There were no Earth-directed CMEs observed in available satellite imagery.

Forecast: Solar activity is expected to be at very low levels with a slight chance for C-class activity over the next three days (06-08 Jul).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at normal levels over the next three days (06-08 Jul). The greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels. Solar wind speeds were between 300 and 360 km/s. Total field was between 1 and 8 nT, and the Bz component was mostly variable. The phi angle was negative.

Forecast: Nominal to near-nominal levels are expected the next three days (06-08 Jul) under mostly background solar wind conditions.

Geospace

24 hr Summary: The geomagnetic field was at quiet levels.

Forecast: Mostly quiet levels are expected for the next three days (06-08 Jul) with a chance for unsettled levels on days one and two (06-07 Jul) as a result of a passing negative polarity CH HSS.
